What was the reasoning behind implementing the app this way? It's the only app I can think of that takes control of your phone's or tablet's audio and prevents you from turning it off. I can't think of a use case other than "annoy the crap out of our users," so please enlighten us.
Alternatively, you could just FIX IT.
I just wanted to update everyone and let you know that there is now an option to disconnect from the audio in our Apps. You can return to view the meeting and reconnect or dial-in at any time. We have also implemented this option in the latest versions of our desktop software.
